55 Years of Clarity Captured
In 1971, three people needed a tool that didn't exist, so they built it. Today, solving real-life problems is still our guiding principle. We help organizations securely capture, preserve, manage, and understand the mission-critical communications they rely on when accuracy and clarity matter most.
Secure Recording and Operational Intelligence
Eventide Communications has spent more than 55 years building recording technology for organizations that need an accurate account of what happened and reliable access to it when the time comes.
Founded in 1971 in New York City, Eventide began by developing recording technology for broadcasters. Early systems helped radio stations continuously record programming for quality monitoring and commercial verification. As 911 services expanded and public safety agencies needed something no one had built well – a secure way to capture what happened in a specific incident with reliable access to recordings – Eventide applied its recording expertise to a new set of requirements where a missing second could affect an investigation, a court case, or even a life. That work became the foundation for Eventide Communications today.


Secure recording and operational intelligence for public safety, air traffic control, healthcare, defense, utilities, transportation, and other organizations responsible for mission-critical and critical communications.
More Than 55 Years of Recording Experience
Eventide Is Founded: 1971
Eventide started in the basement of Sound Exchange, a small recording studio in Manhattan. Recording engineer Steve Katz had no room for a tape operator, so inventor Richard Factor built a device that could rewind the tape to specific points. Studio owner Orville Greene, a businessman and patent attorney, paid for the first unit. Eventide was born, developing recording technology for broadcasters and helping radio stations continuously capture programming for quality monitoring and commercial verification.

Eventide builds Argus, the first moving map for general aviation, giving all pilots the situational awareness once reserved for military and airlines only.
